HYDROCARBON BURNER.

Application led February To all whom it may concern:

Be it known that I, ADOLPH A. HALTER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Hydrocarbon Burners; andI do hereby declare the following to be a full, clean-and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a burner particularly adapted for coal oil orother liquid hydro-carbon fuel which does not readily volatilize.

It is aimed to provide a novel and generally improved constructionwherein preheated air will mix with the fuel so that the combustiblemixture will reach the burner in a gaseous state.

It is further aimed to provide in such a burner, a novel drop-feed meansto discharge or supply the coal oil at the point of admiXture with theair, and with the air supply means arranged to be preheated by theburner.

Still another object is to provide a construction in which the fuel andair supply pipe are compactly arranged in a nove'll manner and with theformer supporting the burner.

Various additional objects and advantages will become apparent vfrom aconsideration of the description following taken in connection withaccompanying drawings illustrating an operative embodiment.

In said drawings z-f 1 Figure l is a side elevation of the burner;Figure 2 is a plan view thereof;

Figure 3 is a central vertical section;

Figure 4 is an enlarged vertical section particularly through the burnerand adjacent portions of the fuel and air supply Figure 5 is a rearelevation ;l and Figure 6 is a cross sectional view on the line 6-6 ofFigure 1.

Like reference characters designate like or similar parts in thedifferent views.

In carrymg out the invention, a main or feed pipe is provided at 10having an inlet opening at 11 from which a rod 12, preferably ofaluminum, extends forwardly and downwardly and terminates and is free atthe front end of said main pipe 10.

A suitable casing 13 is secured at the real` 8, 1923. Serial No.617,742.

of the main 10 and aA pipe 14 communicates therewith and also with asource of fuel such as coal oil or other liquid hydro-carbon which willnot readily vaporize or volatilize.

Adjustably mounted in the casing 13 is a valve stem 15 for which theopening 11 constitutes a seat. Valve 15 is threaded to the casing or apart thereof as at 16 and is adapted to be manipulated through themedium of a knob or handle at 17. Through the adjustment of the valvestem 15, its' position with respect to the valve seat 11 is adjustableso as to increase or diminishv the supplyof oil or fuel to the main 10.The

fuel is admitted to main 10 only in such a quantity that it will Howalong the rod 12 and drop therefrom at its free end.

A Ycoupling 18 at 19 is screw threaded to the front end of the main 10.Its

zle 14 may be surrounded by a cylindrical 80 removable and replaceablewick 25.

Screw threaded as at 26 into the branch 21 is an air supply pipe 27which is open -and spaced from the pipe 23 at 28 to facilitate theintake of air. Generally, the pipes 23 and 27 selectively form a loop'as shown. The rod 12 at its free end is disposed at the entrance tobranch 20 and pipe 23.

A burnerA of suitable design is employed as at 29, being cast integralwith the pipe 27 or provided in any other way and preferably having anupstanding, cylindrical Vwall 30 through which the pipe 27 passes sothat the combustible `mixture emitted from the nozzle 24 will passupwardly through the 95 cylinder 30 about the portion of pipe 27 withinthe burner and then discharge through outlet orifices 31 in the top wallof the burner.

In use, the valve stem 15 is yregulated 100 through the medium of knob17 to enable coal oil or other fuel to enter main 10 by traveling alongthe rod 12 and then dro ping therefrom into the pipe 23 and nozzl,

24 and then on to the wick 25. Initially, the 10U main 10 may be floodedso that the coal oil may better reach the wick 25. When said wick 25 issaturated, the fuel is ignited so as to warm the air which is drawn inor syphoned at opening 28 and through pipe 110 27 incidental to flow ofthe fuel from the main 10. After the apparatus has thus been VmV (E 'mastarted and .is sufficiently warm, the flame at the yWick isextinguishedV and the air passing through pipe 27 will engage the fuelas it drops from the rod 12, thoroughly miXing With it and gasifying andas a gas passing through the pipe 23 to nozzle 24 and discharging fromthe latter into the burner 29 and being ignited at the orifices 3l.

As merely one operative embodiment has been illustrated and described,it is understood that changes in the details may be resorted to providedthey fall Within the spirit and scope of the invention.

Nhat is claimed is 1. A burner of the class described having a fuelsupply pipe and an air supply pipe `.collectively forming asubstantially endless gure,said pipes at one end being in communicationwith each other, means to sup ply fuel tothe fuel supply pipe, the airsupply pipe being open at its other end, the fuel supply pipe having anozzle adjacent the last mentioned end extending towards and terminatingshort of the air supply pipe, and a burner on the air supply pipeopposite said nozzle.

2. A burner of the class described having a fuel supply pipe, means tofeed fuel thereto, an air supply pipe to discharge air adjacent theentrance of said fuel supply pipe to gasify the fuel, a burner on thevair sup ply pipe surrounding a portion ofthe same,

and a discharge nozzle on the fuel supply pipe associated With saidburner.V

3. A burner of the class described having a fuel supply pipe, means tofeed fuel thereto, an air supply pipe to discharge air adjacent theentrance of said fuel supply pipe to gasify the fuel, a burner on theair supply pipe surrounding a portion of the same, a discharge nozzle onthe fuel supply pipe associated with said burner, said nozzle eX-tending toward the air supply pipe, and the free end of said air supplypipe being located adjacent said nozzle.

4.' A burner of the class described having a main pipe, a couplingthereon having branches, a fuel supply pipe leading `from one of saidbranches, the free `end of said fuel'supply pipe terminating in anozzle, an air supply pipe extending from the other branch and beingopen adjacent said nozzle,

and a burner on said air supply pipe adtranceof the fuel supply pipe,the free endy of said fuel suppl-y pipe having an upstanding dischargenozzle, an air supply p ipe open adjacent said nozzle, and a burnerpartly surrounding said air supply pipe'and disposed thereon incooperative relation to said nozzle.
